[Solved] Kernel 2.6.24 and Benq DVD Drive

Hello,

I have a Benq DW1650 DVD burner and it has disappeared since the 2.6.24 kernel came out.  I have verified by reverting to 2.6.23 and it reappears. 

dmesg shows hundreds of these:

hdc: status error: error=0x00 { }
ide: failed opcode was: unknown
hdc: drive not ready for command
hdc: status error: status=0x59 { DriveReady SeekComplete DataRequest Error }

There is a workaround that has brought it back for me on the Ubuntu forums:

https://bugs.launchpad.net/ubuntu/+sour … bug/182996

It is basically a reset and then reactivate DMA:

hdparm -w /dev/hdc
hdparm -d1 /dev/hdc

It seems to only be a problem for some drives.

Workaround worked to me (BENQ) but after reboot error showed up again. Is there any way on how to solve that permanently?

What is your mkinitcpio configuration ? I suspect you still use ide ?

I have a similar DVD drive (Benq DW1655) ... which doesn't show the issue with pata (nforce mcp55).

Try to switch over to pata (the new ide drivers) and see if it helps you.

Info:

The biggest caveat with switching over to pata is the change of the device names from hdX to sdY.

Not helped. Still reseting manually on each boot. Well, maybe I should be patient and wait for another kernel update ?

Thanks anyway vogets !

Thanks a lot vogets, the pata hook was what I needed.

Good luck Mulac.  Did you remember to generate the initrd after the config change? mkinitcpio -p kernel26
